Edmonton, Canada (My Sportsbook) - Scott Dixon won Saturday's inaugural Rexall Edmonton Indy at the Rexall Speedway located at City Centre Airport. The No.9 Target Chip Ganassi Racing driver crossed the finish line 5.9237 seconds ahead of Helio Castroneves.

The victory was Dixon's fifth of the season and 15th of his IndyCar career.

"I think at this point in the championship battle, it's a must-have for Team Target," said Dixon, who became the fourth driver in IndyCar Series history to reach five victories in a season. "Helio has been very strong in the last two races. He's been trying to chase us down, but we were able to make a small gain on him this weekend."

Justin Wilson, Paul Tracy and Oriol Servia completed the top-five.

Tony Kanaan was leading Dixon and A.J. Foyt IV when Graham Rahal crashed on lap 61. Kanaan and AJ Foyt IV, both on different pit strategies, gave up their respective spots on the track to take their final stops.

With Kanaan in the pits, Dixon took over the race lead. Castroneves, Dan Wheldon, Tracy and Wilson followed behind the leader when the race went back to green on lap 65.

Dixon and Castroneves pulled away from the field on the restart. And it became obvious that this race would be a battle between Dixon and Castroneves.

The No.9 TCGR driver held a 0.4779-second margin when the race became timed. There was just over nine minutes left.

Things got a bit interesting when Dixon hit lap traffic with five minutes remaining. Castroneves cut into Dixon's lead and had thoughts of passing. But Castroneves ruined any shot he had at winning the race when he locked up his brakes.

"When you're behind another driver, you're just short on tires," said Castroneves. "I was doing everything I could just to keep up. I was pushing and trying to put pressure on Dixon with every lap, but he never made a mistake. I'm just going to keep working hard because it isn't over for Team Penske yet."

Dixon took full advantage of Castroneves' mistake. Dixon built a comfortable gap and cruised past the finish line.

Pole winner Ryan Briscoe led the 27-car field around the 1.973-mile, 14-turn temporary street/airport course to the green flag for a scheduled 95 laps of racing.

The No.6 Team Penske driver led for three laps before teammate Castroneves took over first. Castroneves pulled away to over a three-second lead. Servia, Dixon and Wilson followed behind.

The first caution flag of the race flew on lap 19 for a Vitor Meira crash. Castroneves led the leaders down pit road for their first pit stops.

Marco Andretti, Tony Kanaan and Buddy Rice inherited the first three positions by not stopping. Castroneves and Briscoe followed behind in fourth and fifth, respectively.

The race went back to green flag conditions on lap 24. Castroneves quickly got past Rice for third. Hideki Mutoh brought out the second caution flag on lap 29. Kanaan and Rice made their first stops under the caution period. Andretti decided to stay out again.

Andretti led Castroneves, Briscoe, Dixon and Servia to the lap 33 restart. Castroneves got a great restart and ducked to the inside of Andretti and passed for the lead.

Castroneves quickly built over a three-second margin. Andretti lost another spot when Briscoe passed him on lap 38. Andretti came into the pits a few laps later for his stop.

The No.3 Team Penske driver was dominating the race as he pulled away to over a seven-second lead. His huge gap was erased on lap 49 due to a Townsend Bell crash. The leaders came down pit road for their second stops of the day.

Kanaan, Foyt IV, Rice and Ed Carpenter, all on a different pit strategies, inherited the top-four spots by not stopping. Castroneves completed the top- five.

The race went back to green on lap 55. Briscoe and Wheldon made contact and lost numerous spots. Briscoe came into the pits a few laps later to check for damage and get fuel. Meanwhile, Kanaan and Foyt IV traded the first position back-and-forth. On lap 60 Kanaan and Dixon got past Foyt IV, who was leading.

The caution flag came out on lap 61 and Dixon would take over the lead when Kanaan hit pit road.

With the victory, Dixon now leads Castroneves in the standings by 65 points. Wheldon trails in third by 115 points.

"At this point, I think a 65-point lead is pretty strong. We just have to keep on it for the next four races. We need to be consistent and continue to earn points. This win was definitely a turn for us in the championship," said Dixon.

The next race in the series is set for Saturday, August 9th at the Kentucky Speedway.
